show that using the object interface saves 1 microsecond per key, spread across all 5 operations performed on each key/value, Say 1/5th of a microsecond (0.0000002) per operation. You need to be doing billions of hash operations -- with almost no other associated processing -- for that to become a significant part of your time costs.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

At least to me, this really busts the "Tied Hashes are Expensive" myth, so the decision whether to use tied hashes or an object interface should definitely not be based on performance, but rather on matters of style and clarity. Thanks again!
